2.4.2.2. Compressor
1. Check if the Daikin unit is connected to earth.
2. Check if the stop valve is open.
1. Switch off the Daikin unit via the user interface.
2. Switch off the Daikin unit with the field supplied circuit breaker.
3. Remove plate work when required (refer to
"Basic removal" on page 67
).
4. Open the compressor insulation.
5. Check if the condition of the compressor dampers and piping is correct.
1. Switch off the Daikin unit via the user interface.
2. Switch off the Daikin unit with the field supplied circuit breaker.
3. Remove plate work when required.
4. Open the compressor insulation.
5. Switch on the Daikin unit and measure the U, V, W inverter voltages. All voltages must be identical, if not, replace the inverter
PCB.
6. Switch off the Daikin unit via the user interface.
7. Switch off the Daikin unit with the field supplied circuit breaker.
8. Disconnect the Faston connectors U, V and W from the compressor, take picture.
9. Measure the compressor motor windings U-V, V-W and U-W (refer to
"Product specific information" on page 121
).
10. Megger the compressor using 500 or 1000 VDC, the insulation must be higher than 3 M
Ω
.
11. Replace the compressor if the windings and/or insulation measurements fail (refer to
"Replacing compressor" on page 76
).
12. Run the compressor and measure the current in each phase; the current for each phase should be identical (refer to
"Product
specific information" on page 121
). In that case it can be decided to preventively replace the compressor (refer to
"Replacing
compressor" on page 76
).
